cds-question@unistra.frcataclysmic-variable-starsvisible-astronomysloan-photometryorbitsWe present a catalogue of 507 cataclysmic variables (CVs) observed in SDSS I to IV including 70 new classifications collated from multiple archival data sets. This represents the largest sample of CVs with high-quality and homogeneous optical spectroscopy. We have used this sample to derive unbiased space densities and period distributions for the major sub-types of CVs. We also report on some peculiar CVs, period bouncers and also CVs exhibiting large changes in accretion rates. We report 70 new CVs, 59 new periods, 178 unpublished spectra, and 262 new or updated classifications. From the SDSS spectroscopy, we also identified 18 systems incorrectly identified as CVs in the literature. We discuss the observed properties of 13 peculiar CVS, and we identify a small set of eight CVs that defy the standard classification scheme. We use this sample to investigate the distribution of different CV sub-types, and we estimate their individual space densities, as well as that of the entire CV population. The SDSS I to IV sample includes 14 period bounce CVs or candidates. We discuss the variability of CVs across the Hertzsprung-Russell diagram, highlighting selection biases of variability-based CV detection. Finally, we searched for, and found eight tertiary companions to the SDSS CVs. We anticipate that this catalogue and the extensive material included in the Supplementary Data will be useful for a range of observational population studies of CVs.2023MNRAS.524.4867Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/524/4867CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/350 : Gaia EDR3 (Gaia Collaboration, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/524/4867https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/524/4867http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/524/4867https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/524/4867https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/524/4867http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/524/4867GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/524/4867/tablea1 (CVs from SDSS I to IV (corrected version, 08-Dec-2023))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/524/4867/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/524/4867/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/524/4867/tablea1?GETtext/xml+votable180.050000true0.0614411125.9342150.0055555555555555566/695 733 751 2056 2065 2089 2119 2134-2135 2153 2172 2223 2247 2297 2564 2567 2578 4104 4106 4120 4123 4129 4138 4144 4167 4173-4174 4195 4206 4256 4296 4298 4336 4341 4367 4386 4399 4453 4479 4515 4530 4603-4604 4607 4622 4650 4655 4689 4695 4708 4721 4723 4726 4730 4740 4747 4757 4761 4766 4769 4776 4779 4800 4818 4844 4856 4860 4895 4905 4964 4976 4984 4988 4999 5005 5007 5058 5062 5064 5071 5115 5120 5129 5189 5191 5210 5281 5335 5341 5345 5359 5409 5455 5457 5485 5505 5558 5570 5584 5596 5666 5675 5703 5706 5719 5727 5756 5779 5808 5833 5836 5839 5864 5918 5929 5932 5963 5976 6007 6036 6052 6076 6086 6111 6131 6235 6237 6242 6244 6257 6345 6386 6412 6433 6439 6444 6456 6467 6479 6491 6500 6528 6530-6531 6546 6567 6570 6588 6598-6599 6608 6611 6621 6634 6637 6640 6643 7168 7172 7186 7194 7199 7202 7207 7211 7233 7240 7248 7256 7267 7306 7320 7342 7348 7371 7390 7465 7514 7518 7560 7607 8224 8244 8265 8267-8269 8281 8296 8359 8474 8503 8520 8534 8545 8552 8559 8562 8566 8629-8630 8688 8693 8804 8830 8848 8877 8977 9165 9214 9231 9267 9301 9309 9311 9333 9340 9372 9392 9402 9419 9441 9446-9447 9467 9477 9481 9489 9618 9620 9732 9738 9747 9759 9765 9774 9792 9804 9829 9832 9849 9862 9868 9923 9934 9998 10016 10020 10085 10126 10214 10232 10399 10462 10484 10598 10714 10721 10749 10797 10825 10867 10938 10955 11002 11008 11072 11112 11122 11133 11168 11187 11213 11217-11218 11230 11280 11282 11319 11324 11333 11351 11365 11391 11435 11456 11489 11838 11912 11916 11929 11931 12288-12289 12386 12408 12481 12556 12625 12627 12634 12636 13325 13335 13337 13355 13361 13374 13392 13416 13467 13509 13575 15001 17360 17515 17600 17646 17689 17723 17736 17741 17750 17764 17767 17807 17818 17836 17983 17986 18017 18027 18038 18045 18061 18071 18082 18167 18169 18200 18207 18303 18321 18371 18391 18431 18520 18604 18773 18777 18779 18798 18844 18859 18862 18881-18882 18927 19027 19032 19034 19091 19097 19121 19128 19134 19173 19259 19276 19385 19391 19418 19455 19523 19526 19538 19619 19794-19795 19815 19870 19883 19911 19916 19937 19943 19946 20034 20050 20122 20151 20154 20168 20187 20198 20205 20212 20214 20268 20273 20282 20296 20300 20304 20318 20320 20332 20335 20341 20384 20391 20403 20406 20436 20450 21879 22010 22360 22363 22485 22716 23050 23056 23217 23275 25506 25909 25934 26157 26171 26208 26287 26316 26379 26395 26586 26588 26995 27004 27254 27294 27314 27343 27384 27386 27419 27455 27482 27524 27545 27612 27671 27779 27956 27975 27982 28047 28082 28104 28127-28128 28194 28221 28396 28423 28501 28561 28616 28627 28633 30041 30044 31145 31309 31321 31331 31357 31397 31464 31617 31642 31652 31684 31689 31699 31715 32408-32409 32417 32432 32436 32480 36719 49100 49120 49123 491293.588997330618193e-19 4.653515163505597e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/524/4867?format=asciiOpticaldefaultJ/MNRAS/524/4867/tablea1CVs from SDSS I to IV (corrected version, 08-Dec-2023)recnoRecord number assigned by the VizieR team.
